SHAFT OR AXLE BEARING.

Specification of Letters Patent.

Application filed .Tune 6, 1912. Serial No. 702,077.-

To all'whom it may concern Shaft or" Axle Bearings, of which the followingis a specification.

This invention relates to bearings for axle journals and rotating shafts and contemplates. the employment of rollers or similar 1 friction reducing devices arranged in a cage external diameter ofwhich is of such dior the'like around the'axle journal or. the

journal of the rotating shaft together with roller bearingsfor resisting endthrust.

In roller bearings as previously proposed, when the rollers become worn and either break or jam, the axle journal or other hearing s'urface'is no longer supported in a proper manner.

The improved arrangement constituting the presentinvention has for its object to avoid these disadvantages by providing in the interior of the bearing a steel sleeve,-the

mensions that the rollers accurately engage with the surface of the sleeve so asto rotate thereon, the internal diameter of the sleeve being the. same as the diameter of the axle journal or of the bearing surface of the shaft. Thebearing being placed in position on the journal of the shaft from one end is .-f s'o arranged that there is no play between the interior of the sleeve and the 'ournal or bearing surface, the sleeve being, however,

so arranged as to be capable of rotating on the journal if necessary. Under normal conditions the external surface of the steel sleeve is carried around by the journal or bearing surface upon'which it is mounted and rotates within the interior of the roller cage; in the event of an accident to one ormore of the rollers so that the rotation of the sleeve can no longer take .place freely within the roller cage, the friction thus created between the rollers and the sleeve causes the latter to remain stationary relaternal sleeve of the bearing without damage.

A further important feature ofthe inven- Patented May 26, 1914-.

A which is accurately fitted to the bearing surface of a journal B. The sleeve A can, if required, rotate about the journal B, but does not normally rotate on the j ournahits external surface serving as a rolling surface for the cylindrical rollers C mounted. in' 'a cagej these rollers are maintained in posi tion in the longitudinal direction by narrow external retaining rings a. The rollers G are arranged in a cylindrical cage D, which is located inside a cast iron housingE, such as is ordinarily employed on railway vehicles. The cylindrical rollers C thus rotate between the stationary cage D and the sleeve A which is rotated by the axle journal. At the two ends of the bearing conical roller guides m are radially arranged, these rollers a; being located in an annular cage e; that pivot of each roller a: which is adjacent to the larger end of the roller, as will be seen from Fig. 2, is adapted to rotate freely within the outer flange of the cage e the other pivot being retained in position by a ring 7 firmly secgred to the inner flange of the cage.

- The stationary'cage; D in the interior of which the cylindrical rollers C rotate, is'not made in a single piece, but is divided into three portions. a middle portion D and two side portions D D which are of T-shaped cross section; the latter sections constitute flanged rings 'screwthrcaded ontheir outer At one side of the axle wheel, that is tosay on the inner side of the journal B (right hand side of Fig. 1), on which the rotatable sleeve Ais mounted, the annular ca shoulder 72 of the axle; on the cylindrical part Q of the axle the ring 1S mounted and rigidly secured thereto and an annular cup leather 8 engaging with the external surface 'of the ring 1=, the cup leather 5 being located iu a groove formed in the oil box E, thus hermetically sealing the bearing and preventing the entrance of dust. On the outer end of the journal (left hand side of Fig. l) the annular cage 6 containing the conical rollersm which engage-with the flanged ring D is retained inposition by a collar '6 formed in two semicircular parts which when assembled together are engaged in a groove 26 formed on the'extremity of the'journal. At this end the oil box is closed by a bolted cover o, witha packing ring 3/ of leather or other ,material interposed forming a hermetic joint. 7

A removable plug for drawingoil from the oil box E is provided at z adjacent to r the end of the journal.

The rotatable sleeve A, instead of being made in one piece is preferably formed in three parts to facilitate manufacture, the joints of the various portions being arranged adjacent to the rings a which guide and securein position the cylindrical rollers C.
